Another approach is to use a bandpass filter to attenuate all signals outside the desired band.
Multiple AP radios can co-exist in proximity to each other with only very minor
interference. Each network address has a different hop pattern. Additional isolation can be
achieved by using separate directional antennas with as much vertical or horizontal
separation as is practical.
If constant interference is present in a particular frequency zone, it may be necessary to
“skip” that zone from the hopping pattern. The radio includes built-in software to help you
identify and remove blocked frequency zones from its hopping pattern. See Skip Zones
Menu for more information.
If interference problems persist even after skipping some zones, try reducing the length of
data streams. Groups of short data streams have a better chance of getting through in the
presence of interference than do long streams.
The power output of all radios in a system should be set for the lowest level necessary for
reliable communications. This lessens the chance of causing unnecessary interference to
nearby systems.
